WILLIAM HENRY BRADLEY, OF SAN FRANCISCO, CALIFORNIA.

OIL-BURNER.

To all whom it may concern:

Be it known that I, WILLIAM HENRY BRADLEY, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented new and useful Improvements in Oil-Burners, of which the following is a specification.

This invention relates to oil burners, and particularly to an oil burner to burn crude oil and other hydrocarbons.

It is one of the objects of the present invention to provide a substantial, eective and sectionally constructed oil burner in combination with means for providing a variable quant-ity of air either under natural or forced draft to the burner.

The invention consists of the parts and the construction and combination of lparts as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which- Figure 1 is a front elevation of the improved burner as adjusted in a range. Fig. 2 is a sectional view of the combustion chamber.

In the illustrated embodiment of the invention there is shown a substantially cylin drical chamber 2, having a bottom flange 3 and a closed lower end 4 which is perforated to receive a pipe 5, whereby air under pressure may be applied when necessary to the chamber of cylinder 2, which is here shown as resting in the fire boX o-f a stove or range 6.

The upper end of the chamber 2 is pro vided with an annular flange 7 to which may be attached, as by bolts 8 or other means, a superposed section or combustion chamber 9, the body portion of which'may be of substantially uniform diameter with air chamber 2.

The spaces formed in the sections 2 and 9 will freely communicate with each other through abutting ends of the air chamber 2, and the superposed section 9 being open for the free passage of air from the lower to the uppermost section in which, at a suitable height above the plane of its lower end is formed an oil pan 10, the greater portion of which is surrounded by an upwardly projected flange 11, sufficiently spaced from the Walls of section 9 to provide a flue or passage way 12 through which air from the Specification of Letters Patent.

lower section 2, may flow upwardly and around the oil pan 10.

The front of the cylindrical section 9 of the oil burner is provided with a segmental aperture or mouth 13, into which may be projected an oil feed pipe 14, the mouth 13 being closable by circumferentially adjustable gates or shutters 15, mounted in suitable guides 16 formed on the circumference of t-he burner section 9 which may be designated as the combustion chamber.

The air chamber 2 of the burner is provided with a segmental mouth or aperture 17, over which are adjustable shutters 18 which may be opened or closed as desired to admit a quantity of air to enter into the lower section 2, and when the shutters 18 pipe 5.

When the burner thus constructed is to be applied within the fire box of a stove, range or other apparatus, proper connections are made as by the air pipe 5 to supply air, and by the pipe 14 to supply oil to the burner, and the latter when admitted through the pipe 14 will be deposited on the oil pan 10 of the combustion chamber 9 of the burner, and when suflicient heat has accumulated in the burner or stove the oil will thereafter be rapidly consumed as it issues from the oil pipe 14, the upwardly rising current of air from the air chamber 2 thoroughly commingling with the gas produced by the burning oil, the heat and dame from the burner issuing from the upper portion of the oil burner section 9 into the range.

The combustion chamber 9, is provided at its upper end with a flange 19 to which may be connected an uppermost flue or waterjacket 20, by which the products of combustion and heat in the burner may be conveyed to a higher point in the stove, and at the same time the waterj acket 2O when provided with circulating water will impart to the latter a suitable increase in temperature.

Manifestly the burner may be used in various applications and environs and will operate effectually under natural pressure without the use of the air feed pipe 5, and when so used the air dampers 18 are adjusted so as to permit the proper quant-ity of air to enter the air sectional chamber 2 of the burner, thus supplying sufficient oxygen to permit combustion of the oil in the pan 10.

Having thus described my invention, what I claim and desire to secure by Letters Patent isl. A hydrocarbon burner, comprising a lowermost section or air chamber having a segmental mouth with adjustable covers, a combustion chamber superposed upon and alined with the lower chamber and having a transversely disposed oil pan, said pan having a concentric flange spaced from the inner wall of the combustion chamber to form an air passage about the pan, and means for supplying fuel oil to the oil pan.

2. A hydrocarbon burner, comprising` a lowermost section or air chamber having a segmental mouth with adjustable covers, a combustion chamber superposed upon and alined with the lower chamber', said combustion chamber having an air inlet and having a transversely disposed oil pan, said pan having a concentric llange spaced from the inner wall of the combustion chamber to form an air passage about the pan, means for supplying fuel oil to the oil pan, and adjustable shutters covering the air inlet in the combustion chamber.

3. A hydrocarbon burner, comprising a lowermost section or air chamber having a segmental mouth with adjustable covers, a combustion chamber superposed upon and alined with the lower chamber and having a transversely disposed oil pan, said pan having a concentric flange spaced from the inner Wall of the combustion chamber to form an air passage about the pan, said combustion chamber having an air inlet, means for supplying fuel oil to the oil pan, adjustable shutters covering the air inlet in the combustion chamber, and a device for supplying compressed air to the lowermost section of the burner.

A. A liquid fuel burner comprising an air section, a combustion section superposed upon and alined with said air section, said sections having flanges for detachably securing the sections together, said sections each having an air inlet, regulators mounted on each of said sections for varying the quantity of air admitted to the interior of the respective sections, an oil pan transversely mounted in the superposed combustion section and having an tip-turned flange forming a segmental passageway within the walls of the combustion section, and an oil supply pipe for delivering liquid fuel to said pan.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
